Dinosaur Extinction and Survival

The video, presented by Sarah, explores the extinction of dinosaurs, which occurred 65 million years ago. It discusses the diversity of dinosaurs, including those with feathers that resembled birds. The video highlights the meteorite theory as the most credible explanation for their extinction, which led to dramatic climate changes. Despite this, some species like birds and crocodiles survived. The video concludes with a friendly farewell from Sarah.
